A single Legionella pneumophila genotype in the freshwater system in a ship experiencing three separate outbreaks of legionellosis in 6 years.

Background: Recurrent legionella outbreaks at one and the same location are common. We have identified a single Legionella pneumophila genotype associated with recurrent Legionella outbreaks over 6 years.

Methods: Field emergency surveys following Legionella outbreaks were performed on a vessel in 2008, 2009 and 2013.

Legionella pneumophila in Norwegian naval vessels.

Background: Little is known about the occurrence of Legionella pneumophila in water supply systems on board ships. Our aim was to study the occurrence of L. pneumophila in the water supply system on board Norwegian naval vessels as the basis for framing preventive strategies against Legionella infection.

Concentration of circulating autoantibodies against HSP 60 is lowered through diving when compared to non-diving rats.

Objective: Skin and ear infections, primarily caused by Pseudomonas aeruginosa (P. aeruginosa), are recurrent problems for saturation divers, whereas infections caused by P. aeruginosa are seldom observed in healthy people outside saturation chambers.

Development and evaluation of a new PCR assay for detection of Pseudomonas aeruginosa D genotype.

This report describes a new PCR-based assay for the detection of Pseudomonas aeruginosa genotype D in occupational saturation diving systems in the North Sea. This genotype has persisted in these systems for 11 years (1993-2003) and represents 18% of isolates from infections analysed during this period. The new PCR assay was based on sequences obtained after randomly amplified polymorphic DNA (RAPD)-PCR analysis of a group of isolates related to diving that had been identified previously by pulsed-field gel electrophoresis (PFGE).

An in-field demonstration of the true relationship between skin infections and their sources in occupational diving systems in the North Sea.

Introduction: Skin infections in saturation diving are caused by microbes that flourish in saturation environments. Improvements in the prevention of infections must therefore be based on environmental control and elimination. Furthermore, only a few genotypes seem to be responsible for the majority of infections in the Norwegian sector of the North Sea, and these have all been demonstrated in saturation systems for many years.

Relationships between indoor environments and nasal inflammation in nursing personnel.

In this study, the authors sought to address the relationships between measured indoor environmental factors and nasal patency (i.e., minimum cross-sectional area) and volume and markers of nasal inflammation in nasal lavage fluid.

Sign of eye irritation in female hospital workers and the indoor environment.

The relationships between indoor environment factors and signs of eye irritation were studied in a sample of female personnel with (n = 112) and without (n = 64) mucous membrane symptoms working in 36 nursing departments at geriatric hospitals in the municipality of Trondheim, Norway. The indoor climate was characterised by high room temperature (interquartile range 23.0-23.

The impact of environmental Pseudomonas aeruginosa genotypes on skin infections in occupational saturation diving systems.

Skin infection caused by Pseudomonas aeruginosa is the most frequent health problem associated with occupational saturation diving on the Norwegian continental shelf. In the course of 14-y surveillance of infection and environmental control in occupational offshore saturation diving systems, a collection of approximately 1000 P. aeruginosa isolates has been amassed.

Survival of infectious Pseudomonas aeruginosa genotypes in occupational saturation diving environment and the significance of these genotypes for recurrent skin infections.

Background: Occupational saturation divers suffer from various skin disorders, of which skin infections are the most serious and frequent. Pseudomonas aeruginosa is the microbe most often isolated.

Methods: P.

Identification of infectious Pseudomonas aeruginosa strains in an occupational saturation diving environment.

Objectives: Occupational saturation divers have various skin disorders, of which skin infections are the most serious and frequent. Pseudomonas aeruginosa is the microbe most often isolated from skin infections in divers. The purpose of the present work was (a) to report the occurrence of P aeruginosa in skin infections in operational saturation diving in the North Sea from 1987 to 1995; (b) to report the environmental occurrence of P aeruginosa in saturation diving systems, and finally (c) to identify possible relations between infection related to strains of P aeruginosa and environmental isolates of the microbe.

Diver's hand: a skin disorder common in occupational saturation diving.

Saturation divers regularly inspect North Sea installations, working at depth for periods of 12-16 days. Diver's hand is a particular problem in saturation diving, and there is no effective protection or treatment available. This paper presents the occurrence of diver's hand and describes the disease in clinical and epidemiological terms.
